Lightweight Design Solutions

Process development process:

Demand analysis and design solution: Through in-depth analysis of the working conditions of concrete pump trucks, engineers found that during the concrete delivery process, the bends are subject to strong impact and friction from concrete particles, causing rapid wear, so higher wear resistance is required. The two ends of the bends are subject to relatively less wear, so they can be appropriately thinned. Based on this analysis, the team proposed a lightweight design solution to optimize the structure by thickening the bends and thinning the two ends.

Material selection and optimization: On the premise of ensuring wear resistance, the team continued to use high chromium cast iron as the main material for the bent pipe. High chromium cast iron is widely used in wear-resistant castings due to its excellent wear resistance and hardness. In order to further optimize, engineers adjusted the alloy composition of high chromium cast iron to ensure that the material properties in the thickened part are optimal while ensuring that the strength and toughness of the thinned part are not affected.

Structural optimization and simulation testing: In the lightweight design, the team used finite element analysis (FEA) tools to conduct detailed stress analysis and wear simulation on the elbow structure. Through simulation testing, it was verified that the thickened bend design can effectively extend the service life of the elbow, while ensuring that the two ends after thinning will not fail during use due to insufficient strength. The final design reduced the overall weight of the elbow by 15% and increased its service life by 30%.

Manufacturing process development: During the production process, the precision casting process was used to achieve structural optimization of the elbow. Especially in the thickened part of the bend, the team adjusted the casting mold and cooling process to ensure the density and uniformity of the material structure and prevent casting defects. In the thinning part of the elbow, the casting thickness and heat treatment process were controlled to ensure that it has sufficient strength and toughness.

Performance testing and application: After manufacturing, the elbows were subjected to rigorous performance testing, including wear resistance, impact resistance and pressure testing. The test results showed that the lightweight elbows not only met the high wear resistance, but also had a significantly reduced weight, meeting the expected design goals. According to customer feedback under actual working conditions, the service life of the new elbows was 30% longer than that of traditional elbows, while reducing the overall energy consumption and operating costs of the pump truck.
